4. Edit {pub}/xslt/page2xhtml.xsl
ADD:
<xsl:apply-templates select="xhtml:div[@id = 'tabsall']"/>where you want the tabs to appear, probably replacing:
<xsl:apply-templates select="xhtml:div[@id = 'tabs']"/>The file must include the default "copy everything not specified" match:
<xsl:template match="@*|node()" priority="-1">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>If that has been removed, use a mode to apply it just to this.

5. Add the CSS from tabsall.css to your website. You can either:
A. Add the contents of tabsall.css to {pub}/resources/shared/css/page.css, or
B. Place tabsall.css in {pub}/resources/shared/css/ and add the following line to your HTML in page2xhtml.xsl:
<link rel="stylesheet" href="{$root}/css/tabsall.css" type="text/css"/>
